This invention relates to stove doors, and has to do particularly withthe oven and broiler doors of gas and vapor ranges.

, In recent years, stove ranges of the better class have been sofabricated and finished that all of the exposed surfaces have beenenameled. As a result of this practice,.practically all of the betterclass stove ranges on the market present a very pleasing appear anoe andat the same time are very sanitary in that substantially all surfacesmay be easily cleaned and because of such enameled surfaces, all greaseand other foreign matter may be readily seen.

As the general appearance of an enameled range depends to a large extentupon the design and fabrication of the doors, considerable attention hasbeen paid to the forming and enameling of the stove doors and heretoforeit has been thegeneral practice, in the better stoves, to form oven andbroiler doors of cast iron so as to accentuate the various lines andfeatures of the particular design embodied in the stove as a whole.However, such cast iron and enameled doors have not only been expensiveto manufacture but have had their limitations in ornamental design.

It is the object of the present invention to provide a pressed metaloven door which retains all of the better features and qualities of thecast iron door but which presents a door much easier to fabricate andenamel and which makes possible the forming of a completely differenttype of ornamental door. This new result is obtained by so fabricatingthe sheet metal door panel to present one or more embossed frames, saidembossed frames providing suitable recesses for receiving completelyseparate panels to complete the formation of the stove door. The stovedoor itself is fabricated in a novel manner both as to the formation ofthe front panel and the back panel.

It, will be understood that the door structure of the present inventionmaybe embodied in substantially any type of range, and in Fig. 1 I haveillustrated a range of the standard type and the design of the noveldoors is shown so as to fit in with this general'standard design.

The stove doors for such oven and broiler openings are fabricated byfirst stamping out a sheet metal frame to define the front of the doors.A portion of such sheet metal frame completely stamped out is shown as'at 3 in Fig. 3, and in stamping out this sheet'rnetal frame an outermoulding or embossed portion 4 is formed to extend completely around anddefine the outer edges of the door. A second molding or embossed portion5 may be formed similarly to the portion 4 but spaced inwardlytherefrom.

Spaced between the embossed frame 4 and the embossed frame 5 is adepressions and defined by the embossed frame 5 is a central depressionwhich may be generally designated 7 The bottom edge of each door ispreferably curved over as indicated at 8 in Fig. 6 whereby to receive asuitable hinge and spring structure and the sides and top of each doorare preferably curved inwardly as at 9 and 10 respectively.

The depressions 6 and Z formed by the embossed panels 4 and 5 may ofcourse take any desired shape and design in accordance with theparticular stove with which they are to be used, the main point beingthat certain embossed frames are formed or pressed out from sheet metalto form a portion of the exposed surface of each door.

In the embodiment shown in the drawings an insert panel 11 is provided,which is perfectly rectangular in shape so as to correspond with and fitin the depression 6 formed between the embossed frames 4 and 5. Thisinsert panel 11 is preferably provided with inturned lugs or projections12 as best shown in Fig. 2, whereby when the panel is inserted in thedepression 6 it will present a well defined outline as well as a verysolid appearance. Said lug members 12 also assist in firmly seating thepanel in the depression.

In order to permit quick assembly of the inserted panel 11, I preferablyprovide suitable apertures 13 spaced around the depression 6 and I alsopreferably secure a plurality of threaded bolts 14 to the back of thepanel 11. These bolts 14 are preferably secured to such panel byspot-welding the same thereto. With the spot-welded bolts or studs 14 inposition on the panel 11 it will be obvious that as a panel is placed inposition in depression 6 that such bolts will protrude through theapertures 13 in order to receive suitable nuts 15 for rigidly securingthe panel in place.

In order to compare favorably with the cast iron door and also to coverup the front panel of each door, I provide a back panel which may begenerally designated 16. This panel 16 is preferably formed from sheetmetal and consists of the dished out portion 17 and inturned peripherialflange 18, such flange 18 contacting with the inner surface of theflange 4, as best shown in Figs. 2 and 5. To permit quick assembly ofthe front frame 3 and the rear panel 16 I preferably provide cornermembers 20 which may be positioned either at the lower corners of eachdoor or at all the corners of each door.

These lower corner members are preferably shaped as shown in Fig. 4 andin case the upper corner members are used they are preferably shaped asalso best shown in Fig. 4. Each corner member 20 is preferably providedwith an aperture 21 which is designed to register with an aperture 22 inthe panel member 16. The flange 18 of the back panel member ispreferably recessed or cut away adjacent each corner of the door wherebyto receive a corner member 20 and this corner member 20 is preferablyflanged as at 23 to form a channel member, the back of which contactswith the inner surface of the embossed frame 4, at the corners.

This channel member 23 may be spot-welded to the inner surface of theframe 4 or one lug 24 of such channel may extend upwardly to contactwith the grooved in portion or portions of the front door frame. I alsoprovide an L shaped lug 25, having a threaded hole 26, and this lug 25is adapted to be fitted into the triangular space defined by cornermember 20 and the sloping surface of the depression 6.

In assembling the front and back panels of the door it will thus beobvious that I only have to insert the L shaped lug members 25 intoposition behind the corner members 20. which may be positioned in eachcorner of the door and then place the back member 16 in place, afterwhich suitable screws 27 may be inserted through the apertures 22 toengage the threaded holes 26 to bring the front panel 3 and back panel16 rigidly and seicurely together.

In the construction of my door members, I preferably subject theembossed frame members 4 and 5 to a nickel plating or chrome platingaction. such embossed frame members making this plating step veryconvenient. The panel member 11 and the inner panel member 28, which ispreferably identical in general fabrication as the panel 11., aresubjected to the usual enamelmg steps whereby to receive a smoothfinished coat of enamel. To assemble the outer door frame beforecomplete assembly of the door it is then only necessary to insert thedesired panels 11 and 28, with their spot-welded studs, into position onthe door frame and then secure such panels in position. It will thus beobvious that any number of door frames 3 may be fabricated with thenickel or chrome plated frames 4 and 5 and that any number of differentcolor combinations of panels 11 and 28 may then be inserted in thedepressions 6 and 7 to complete the door assembly.

In connection with the depression 7, I preferably form suitablepressed-out portions 29 therein whereby to materially reinforce thiscentral part of the front door frame. It will be obvious that thebroiler door and even other parts of the stove may be fabricated andassembled in a manner similar to the oven door, the construction ofwhich is shown in detail. These various doors or other parts of thestove are first fabricated to provide embossed or pressedout framemembers which may be nickel or chromium-plated, and it will be seen thatany number of different insert panels may be enameled with differentcolors or different color-combinations and kept on hand as an availablestock supply. whereby a large number of different combinations may beobtained. In other words. while the main exposed surfaces of the stovemay be of white porcelain enamel and nickel or chromium or any othercolor, the door panels and other parts which may be separatelyinsertable may be of various other color combinatlons to complete thedesign and color scheme of the entire stove.
